                        Chandrayaan-4: The next step in ISRO's lunar exploration ISRO and JAXA are planning a joint lunar mission called the Lunar Pole Exploration Mission (LUPEX), also called the Chandrayaan-4 mission after the successful Chandrayaan-3 mission. Chandrayaan-4 Mission In order to release the Lunar Polar Exploration Mission (LUPEX), also called the Chandryaan-4 Mission, the Indian Space Research Organization (ISRO) and the Japan Aerospace Exploration Agency (JAXA) have teamed collectively. In 2026, the Indian Space Agency (ISRO) and Japanese Space Entity (JAXA) aim to launch the Chandryaan-4 Mission after the a hit touchdown of the Chandrayaan-three moon challenge, with this project India attained astounding accomplishment inside the Space Program.   The discovery of water at the moon could drastically affect space exploration inside the destiny and offer a critical resource for maintaining human presence on Earth’s lunar neighbour. The LUPEX is prepared to set n

       Abundant evidence of the Earth's core moving has been found at Baffin Island A joint team of scientists from the Woods Hole Oceanographic Institution and the California Institute of Technology observed evidence of high levels of helium-three in rocks on Baffin Island—potential evidence that the Earth's core is leaking. In their paper published in the journal Nature, the organization describes their observations of helium-3 and helium-4 in the Canadian Arctic Archipelago. Early researchers saw helium-3 elements in lava flows on Baffin Island, suggesting a possible leak from the Earth's core. This is due to the fact that it is an old isotope - it changed conditions over time as the Earth formed and was trapped in the core. But due to its nature, helium-3 that makes its way to the ground quickly escapes into the atmosphere and disappears into space. Thus, helium-three is rare. If it is found on the surface, the percentage is high enough that it has made its way out of t

                   How the Greenland ice sheet can nevertheless be stored Greenland is the world's second largest landmass covered by ice; only Antarctica is bigger. The Greenland ice sheet is greatly affected by the effects of climate change. If the ice melts completely it could cause a sea level rise of more than seven meters - a disaster for coastal areas around the world and for those who live there. Time series of ice volume and spatial extents of the GrIS for warming scenarios without mitigation. a, Sketch of applied warming and cooling scenarios in this study. The warming period lasts for 100 years, followed by varying cooling phases. The black line corresponds to scenarios without mitigation as shown in this figure. b, Evolution of total GrIS ice volume simulated by PISM-dEBM, without reversal of the temperature anomalies (black line in panel a), for different temperature anomalies between ΔTJJA = 0 °C and 7.0 °C above present. The warming period lasts for 100 years until y

                    New styles in sun's layers should assist scientists remedy sun mystery Astronomers are one step in the direction of expertise in one of the maximum enduring solar mysteries, having captured extraordinary facts from the sun's magnetic subject. Small-scale magnetic structures of the ‘quiet sun’ at high resolution His groundbreaking data accrued from the US National Science Foundation's (NSF) Daniel K Inouye Solar Telescope (DKIST) in Hawaii—the most effective sun telescope in the international—has provided the most exact representations thus far of the magnetic discipline of the so-referred to as 'quiet' floor of the sun.   An international team of scientists, which include researchers from the University of Sheffield, believe the facts have implications for the way we model power transfer among the layers of the solar system. The research has been posted in Astrophysical Journal Letters. This may assist give an explanation for one of the biggest c

  Earth's plate tectonics these days underwent a fundamental trade-A New Proof Sampling of a primordial mantle reservoir by mantle plume as evidenced by Ti and Sr isotopic records of the modern OIBs from the Iceland, Samoa and Caroline hotspots. Data of the OIB samples from Cape Verde and Azores in ref. 3 are shown as white circles. The N-MORB and E-MORB samples from refs. 3,4 are shown, for which the N-MORB samples without available Sr isotope data have been assumed to have 87Sr/86Sr = 0.7025. The dotted pink trajectories describe the effects from mixing in increments of 0.2% the ancient marine sediments or continental crust material with δ49Ti = +0.200‰ (refs. 5,6) and 87Sr/86Sr = 0.740 (ref. 47) into a modern depleted MORB mantle source with 87Sr/86Sr = 0.7025 (ref. 63) and δ49Ti = +0.001‰ (refs. 3,4) or into a mantle source with 87Sr/86Sr = 0.7035 and a primordial mantle δ49Ti of +0.052‰. Addition of recycled melting residues would lead to lower δ49Ti values in N-MORBs and some
